TONY Blair's son Euan was rushed to hospital with severe stomach pains during his family's holiday in Barbados.

A doctor visited the PM's eldest child (above), who is believed to have suffered food poisoning, at Sir Cliff Richard's #3million Caribbean home where the Blairs have been on holiday for two-and-a-half weeks.

Mum Cherie and dad Tony then took Euan, 22, to the Queen Elizabeth Hospital in the island's capital Bridgetown where he was kept overnight.

But the Prime Minister jetted back to Downing Street alone yesterday after being advised that his son was in no danger.

Euan - found slumped in Central London in 2000 after a night out - did not have surgery and his condition was not serious, sources said.

He was pushed out of the ward in a wheelchair yesterday and left the building by a rear exit.

Scotland Yard diplomatic protection officers drove Euan back to his mother who was waiting at Sir Cliff's villa.

A spokeswoman for the PM said: "We can confirm Euan Blair was taken into hospital with a stomach complaint."

Euan has two brothers - Nicky, 20, and Leo, six - and an 18-year-old sister, Kathryn, who are also believed to have stayed in the Caribbean.

It is thought Euan would be well enough to travel to the US where he is about to start a masters degree in International Relations at Yale University in Connecticut.

At the age of 16, police found Euan slumped on the ground in Leicester Square. He had been celebrating his GCSE exams.
